Positioned on a desirable street in Reagan's Overlook and backing directly to Garey Park is this rare 1-acre estate that can't be replicated in newer construction. Spanning over 4,400 square feet, this expansive single-story home prioritizes function, flexibility, and everyday livability. The layout includes 5 bedrooms, 4 full baths, a dedicated office, formal dining, and a spacious game room-designed to give everyone their own space without sacrificing flow. Inside, soaring 12', 14', and 15' ceilings with detailed tray accents, 8' doors, and walls of windows create a bright, open feel throughout. The main living areas are both grand and inviting, anchored by a large central living room that connects seamlessly to the kitchen and outdoor spaces. The kitchen is built for both daily use and entertaining, featuring an oversized island, extensive cabinetry, KitchenAid built-in appliances, double ovens, a commercial-grade cooktop, walk-through pantry, and butler's pantry. The primary suite is a true retreat, offering a private sitting area surrounded by windows and a spacious bath with a soaking tub, extended walk-in shower, dual vanities, and an oversized closet. A standout feature is the private guest suite with its own exterior entrance, ideal for multigenerational living, long-term guests, or a true work-from-home setup. The covered patio with fireplace and outdoor kitchen creates a fully functional extension of the home, while the deep, tree-filled acre lot offers endless potential-room for a pool, casita (allowed), and the additional play structures already on site. For buyers comparing to new construction, this home offers what new builds cannot: - A premium, private lot backing to parkland - Mature trees and established outdoor living - Space and flexibility for future expansion - Immediate move-in without the wait or added expense - A rare combination of lot, layout, and location in one of Leander's most sought-after acreage communities.
